Abstract (en)
[origin: EP3780519A1] This application discloses a traffic control method and a related apparatus. When receiving a publish packet sent by a client, a serving end queries a window value of a flow control window of the client, and compares the window value with a preset window threshold. The serving end rejects the publish packet when the window value is equal to the window threshold, or when the window value is greater than the window threshold, decreases the window value by a preset value, and processes the publish packet. When needing to send a publish packet to a serving end, a client queries a window value of a flow control window of the client, and compares the window value with a preset window threshold. The client pauses sending the publish packet to the serving end when the window value is equal to the window threshold, or when the window value is greater than the window threshold, decreases the window value by a preset value, and sends the publish packet to the serving end. This application can avoid a problem that the serving end cannot process, in time, a message sent by the client because the client sends the message too fast when the message is transmitted between the client and the serving end, so that communication can be normally performed.
